Firebrick gives coding agents their own kernel
Firebrick is a Rust CLI that says it runs local coding agents inside disposable microVMs, separating their work from the host machine.

- For
- Developers running local coding agents
- Worth noticing
- The documented flow mounts only the current project folder, then has the agent work in /workspaces/<project> inside a microVM.
Field notes
The illustrated terminal flow starts with `fbk start` in a project folder and then runs an agent through `fbk run claude`. Firebrick says it mounts only that project into the VM, while keys and dotfiles remain on the host; its docs include a Secrets section for passing tokens without placing their real values in the sandbox. The page names microsandbox as its VM foundation and identifies the project as MIT-licensed.
